TaskExecutionException for gradle jettyRun - gradle

Question

I am following the book 'Gradle in Action' page 67 attempting to call:
$ gradle jettyRun
...
* What went wrong:
Execution failed for task ':jettyRun'.
> org/eclipse/jetty/http/HttpField
...
With the --stacktrace option I obtain the following message:
...
* Exception is:
org.gradle.api.tasks.TaskExecutionException:Execution failed for task ':jettyRun'
...
Caused by: java.lang.ClassNotFoundException: org.eclipse.jetty.http.HttpField
...
My project is todo-webapp as per the book page 67:
$ tree
├── build.gradle
├── src
│   └── main
│   ├── java
│   │   └── com

│   │   └── todo-list.jsp
│   └── WEB-INF
│   └── web.xml
and my build file is as follows:
$ cat build.gradle
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'jetty'
repositories {
mavenCentral()
}
dependencies {
providedCompile 'javax.servlet:servlet-api:2.5',
'javax.servlet.jsp:jsp-api:2.1'
runtime 'javax.servlet:jstl:1.1.2',
'taglibs:standard:1.1.2'
}
following various threads online I have been trying to add a dependency to my build file such as:
jettyRun {
dependencies {
providedRuntime 'org.eclipse.jetty:jetty-http:9.4.0.RC0'
}
}
or indeed add the jar directly /usr/share/java/jetty9-http with runtime files(...). None of these worked. I am not too sure what to try next. Any suggestion is greatly appreciated.
EDIT: As indicated by Vampire, all I had to do is remove apply plugin: 'jetty' and instead following the line apply plugin: 'war', add the line:
apply from: 'https://raw.github.com/akhikhl/gretty/master/pluginScripts/gretty.plugin'
Then use gradle appRun instead of gradle jettyRun. All this is coming from the page Getting started of the gretty plugin.

As you can see at https://docs.gradle.org/current/userguide/userguide_single.html#jetty_plugin, the Jetty plugin is deprecated. Maybe you should try the Gretty plugin as suggested in the docs. :-)
